KNOB FOR ELECTRIC GAS-LIGHTlNGAPPARATUS.

SPECIFICATION forming part of Letters Patent No. 311,840, dated February3 1885.

Application tiled December 26, 1853.

T aZZ whom it may concern: I

Be it known that I, FREDERICK LANE, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in 5 Knobs forGas-Lighting Apparatus, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings represent ing like parts.

Myinvention, relating to a gaslighting apparatus,is shown embodied in anapparatus of that kind in which a gas-valve is opened and an electricspark produced by the movement of a lever supported on the gas-burner,the I 5 said lever being usually operated by a small knob or pendantconnected with it by a flexible connector-such as a cord or chain-thesaid knob being within easy reach of the operator. lVhen automaticlighters ofthiskind are employed,it is often necessary or desirable tooperate it in total darkness, as the very object of the apparatus is toavoid the use of matches or torches; and it is at such times verydifficult to find the small knob or pendant. In order to obviate thisobjection, and to render the apparatus much more convenient in use, Ihave provided it with a self-luminous pendant, shown as composed ofahollow transparent bulb provided at its interior surface with self-luminous or phosphorescent material whieh'is protected by the glass fromcontact with the lingers of the operator, and is thus kept clean andpreserved from wear, the bulb having a cap and asuspending-ring, all as5 hereinafter specified and claimed.

Figure 1 represents in elevation a gas-light ing apparatus provided witha luminous pendant in accordance with this invention, and Fig. 2 anenlarged sectional view of the 0 pendant detached.

The burner a, provided with a gas-cock operated by a ratchet, b, and dogor pawl 0, con nected with a lever, c a, may be of any suitable or usualconstruction, various such burnscribing witnesses.

ers being well known. The lever e is pro (X0 model.)

vided with the usual spiL-ingelectrode, f, co-

operating; with an electrode, 9, at the side of the burner-tip, andthearm 0 has connected with it, by a chain or other flexible connection,71, a self-luminous pendant or knob, t, the said pendant being renderedsel filuminous or phosphorescent by any of the usual compounds ormaterials employed for such purpose. The pendant i is constructed asshown in Fig. 2, it being composed of a hollow transparent bulb or ball,i, lined upon its interior with a coating, i", 'otself-luininousmaterial, and provided at its open end or mouth with a metallic cap, ihaving a lug or eye, at, for attaching the chain h, by which thelighting apparatus is operated. A pendant of this nature is readilyvisible in the dark, and can be seized by the fingers ot' the operatorwithout injury to the luminous material, which is "protected by theglass or transparent bulb i, and conse quently does not become soiled orworn off from the pendantby handling, as would be the case if it wereapplied to the outside otthesaid pendant.

I am aware thatln minous or phosphorescent material has been applied toknobs, match boxes or holders, and various other articles which are tobe used in the dark, and hence I do not broadly claim the use of suchmaterial in connection with gaslighting apparatus; but i I claim Thependant ifor a gas-lighting apparatus, composed of the hollowtransparent bulb or ball 0', having the internal protected coating, 1;",of luminous material, the cap i, and eye m, substantially as shown anddescribed.

In testimony whereof I have signed my name to this specification in thepresence of two sub- FREDERICK LANE.
